50 takenalongztheline1i-1 of'Fig'. 2; ToovercomethisI place a baffle 19 between I the two openings and, as Fig. 4 illustrates,

' opening higher as can be done at this point this baffle 19 extends beyond the edge of the openings so that no matter how water is discharged through the opening it will be impossible for it to cross to the other bowl but it will strike the bafile 19 and be deflected 21 must be at least as large'as the opening- 16. I obtain this result by forming the sweep and in this way I am able to obtain more than the area of the opening 16 at the sweep opening. With the area of the opening 16 slightly more than 12 square inches (4 inches diameter) the sweep opening 21 may be formed so as to obtain almost 17 square inches of area. This is done by making the distance from the tip of the baflie to the opposite wall of the fitting three inches, and the height of the opening, that is the distance represented by the broken line a-a in Fig. 5 is 5 inches. This height is obtained by taking advantage of the natural shape of the, fitting at this point, and modifying dimensions slightly.

' One of the most necessary things in the design of this fitting is that the discharge have a clean sweep around the bend so that there will be no obstruction to an even flow, -or

nothing on which any waste matter might'become lodged and so interrupt the discharge movement. To secure this result I provide no'shoulders or the like. at the discharge openings,-that is the openings to which the bowls connect; but the running line connected to the nipple 11 is provided with a continuous flange 22 from a shoulder against which the nipple 11 projects. ,This flange is arranged to besubstantially the same width as the thickness of the nipple.

For securing the bowl to the fitting lugs .2323 are cast on to the fitting'and hinges -24-24are secured thereto by cap screws 2626. The unconnected legs of the hinges are provided with slots through which bolts "2727 ext nd for drawin the horn 28 of the bowl against the end of the fitting. The

usual gasket 29 is provided as a seal at this point. In order to have an adjustment the hinges 24 are provided with slots for receiving the bolts 27 so that they may be regulated with respect to the position of the holes in the 'bowl. In order to support the fitting from the'floor I provide suitable legs on'the fitting and in the preferred form this comprises lugs 31.;formed integraliwiththe fitting support legs 32 and floor flanges 33. In actual practice I have'constructed the legs 32 of ordinary one-half inch pipe, but any suitable support may be employed in this connection.

Any other usual adjusting means may be provided, for any usual way of connecting the bowl may be utilized. The present invention is not meant to be entirely self suflicient but where necessary depending upon the installation may be hooked up with any ofthe present standard plumbing appliances. In installing my fitting the usual methods of roughing in etc. are used, the plaster. being finished to the'fitting as is the custom.

have not attempted to show any particular type of wall construction, as the fitting may be mounted in any standard toilet room partition. Most of these partitions even when employing the floor type bowls are approximately-10 inches in thickness, but I am able to mount my fitting ma 9 inch wall and do away with'lost floorspace entirely.

The fitting of my invention can be em ployed on either a vertical or horizontal waste pipe and is of very great advantage in either case. In mounting iton a horizontal line, there is considerable advantage. in certaintypes of construction particularly where cement-is used because the horizontal waste pipe or running line as itis-called can be roughed in. atthe floor level with the proper pitch and embedded in cement before the closet bowl fittings are installed. Subsequently, these fittings can beplaced' in and the elevation thereof very easily controlledoradjusted forby choosing nipples ll'of suitable length to bring these fittings to the elevation required. Similarly, these nipples 11 can be controlled in length to adjust the position of the fitting with respect to a vertical, line.

While my provision of the baflie 19 is apparently of extreme simplicity, I, found avery great deal of designing andstudy over. a period of years required before Iobta'in'ed fully satisfactory results. It is to be noted'that with the particular manner of supporting the enable those skilled in the art to practice it,

I do not restrict myself to the use of any particular form of fitting except within the scope of the appended claims. 7

What I claim as new and desire to protect by' Letters Patent of the United States is:

1. A plumbing fitting of substantially.

standard T dimensions for mountingjtwo closet bowls backto back comprising .a connection for a soil .or waste pipe oppositely disposed connections for the bowls-communicating with the waste pipe connection, and a bafiie disposed between the closet bowl connections forming sweep openings on both sidesthereof, leading to'the waste pipe connection, each sweep opening having an area at least as large as the opening in the closet bowl connection.

2. A three way fitting of substantially standard T dimensions for connecting closet bowls back to back having a closet connection with the usual circular opening, a soil or waste pipe connection with the usual circular opening,and a baflle between the closet bowl connections extending toward the waste pipe opening, the baffle forming a'relatively narrow sweep opening on each side thereof, each sweep opening being formed higher resulting in an oblong opening having at least the area of the closet bowl openings.

3. A plumbing fitting for mounting closet bowls back to back, said fitting comprising a T with the outward general appearance and dimensions of a standard T fitting, oppositely disposed openings adapted for connection to the closet bowls and a right angularly placed opening communicating with the oppositely disposed openings and adapted by suitable means to be connected to a waste pipe and a baflie between the two closet openings to prevent discharge across from one to the other, the opening at the baffle being oval shaped to have at least the area of the closet openings to avoid any possibility of back pressure into the closets and maintaining the outward size of a standard T fitting so that a minimum amount of wall space is needed to make connections. 7

4c. In a plumbing installation, a fitting for connection to a soil or waste pipe of and having the dimensions and appearance substantially of a standard T, oppositely faced connections for closet bowls, a waste pipe connection communicating with the closet connections, and a baflle between the closet connections for preventing discharge from one bowl to the other and formed to produce sweep openings having at least the cross sectional area of the closet openings, and a pipe nipple for interconnecting the waste opening of the fitting with the waste pipe.

- In witness whereof, I hereunto subscribe my name this 27th day of October, 1928.
